Green Skills–I
Green skills support environmental protection and sustainable development: meeting present needs while caring for resources and future generations.
Core ideas
1. Understand the idea
Sustainable development connects environmental health, social well-being and economic activity.
2. Key knowledge
Reduce, reuse and recycle are useful habits, but reducing unnecessary consumption is often the first step.
3. Apply it
Energy, water, transport, food and waste choices affect environmental impact.
4. Remember the process
A green workplace or school can reduce waste, improve efficiency and choose safer materials.
Worked scenario
A class audits one week of paper use, identifies avoidable printing and proposes double-sided printing plus a shared digital draft. It measures paper use again after the change.
Practice questions with answers
1. What does sustainability mean in everyday decisions?
It means considering whether a choice can meet needs while conserving resources and limiting harm over time.
2. Why measure before and after a green action?
Measurement helps determine whether the action made a difference and whether the result should be adjusted.
Practical evidence
Keep a small practical record: task, tool, steps, result and one learning. For technical units, repeat the operation with a new file or data set so you can explain what changes and what stays the same.
- Can I define the unit’s key terms?
- Can I demonstrate one relevant skill?
- Can I explain a safe, accurate or responsible choice?
